Figure 5.
A: Erlotinib treatment decreased kidney ER stress, as indicated by decreased glomerular and tubule epithelial expression of CHOP, PERK, and BIP in STZ-eNOS−/− mice. B: LC3A immunostaining was detected in tubular epithelial cells, but not in glomerulus, in vehicle-treated STZ-eNOS−/− mouse kidneys. With erlotinib treatment, LC3A expression was detectable in glomerulus and was markedly increased in tubular epithelial cells. Original magnification: CHOP and BIP, ×250; PERK and LC3A, ×400.
